What Weapons do AI-Empires use?

[eagleton]

I like the SE4-demo very much and play it almost every day. Most bugs will surely be sorted out soon and everything's cool.
There's just one thing that somewhat bothers me: The attack ships my AI opponents (those without a special tech-tree like organic etc.) use always have the same three weapon types: depleted uranium cannons, anti-proton-beams and capital ship missiles. I can't remember any of them having used, for example, meson bLasters.
In games with all tech, it's mostly graviton hellbore, wave-motion-guns or sometimes shield damaging weapons.
I think I haven't seen plasma or torpedo after more of a dozen games. Is this because there's only 8 races in the demo who are restricted to these weapons? Is the AI still not advanced enough to use all weapons?
Even when I construct my own AI-opponents, they are restricted to these weapon types, again with the exception of organic, crystalline etc. races.
When I constructed races in SE3, I could choose which weapons they should use. This is not possible in the SE4 game setup menu.
I wish they would change that. SE4 should not give you less choices than SE3 in any area of the game.
